(HealthDay News) -- Transient ischemic attacks (TIAs) are small strokes that often precede a major stroke.
While most strokes aren't preceded by TIAs, if you do have a TIA, you should learn to recognize its warning signs. This can help you and your doctor prevent a major episode that can cause significant and permanent brain damage, the American Heart Association says.
Symptoms of a TIA are similar to those of a full-blown stroke, but they typically last for only a short time. These warning signs can include dizziness, loss of coordination or balance, and numbness or weakness on only one side. Some people may also have difficulty speaking, vision problems, or an unexplained severe headache.
If you have these symptoms, even briefly, see a doctor immediately.
